The use of the word rank for Navy enlisted personnel is incorrect. The term is rate.. The rating badge is a combination of rate (pay grade, as indicated by the chevrons) and rating (occupational specialty, as indicated by the symbol just above the chevrons).
Neurons are nerve cells that are constantly sending signals to your brain, muscles and glands. You have over 100 billion neurons in your brain sending signals. The signals help the different parts of your body communicate with each other.
1 Signals are conducted by the axon from the cell body to the terminal buttons. 2  Signals are transmitted from the terminal buttons to the receiving cell across a synapse (if the receiving cell is a neuron) or a neuromuscular junction (if the receiving cell is a muscle cell). Each terminal button joins to either another neuron, a gland cell, or a muscle cell. 2  The connection to another neuron, which takes place at a dendrite or on the soma, is termed a synapse. 3  When the terminal button connects to a muscle cell, the connection is termed a neuromuscular junction.
